BURNER.

SPECIFICATION forming part of Letters Patent No. 676,374, dated June 11, 1901.

Application filed March 10, 1896.

To all 1071 0122 it may concern:

Be it known that I, ASA W. STRAIGHT, a citizen of the United States, and a resident of Evanston, in the county of Cook and State of Illinois, have invented a new and useful Improvementin Burners, of which the following is a specification.

This invention relates to improvements in gas-burners, and relates particularly to improvements in burners designed for use on blowpipes, gasolene-torches, and the like.

Primary objects of the invention are to pro vide means in combination with a burner to regulate the respective quantities of gas and of air delivered to said burner, so that the proper proportions of gas and of air may be obtained to secure perfect combustion, to provide a burner of such construction that the gas and air delivered thereto will be thoroughly intermingled, and to insure that when gasolene or the like is used for fuel it will be thoroughly vaporzied when delivered to the burner.

. In the preferable form thereof now known to me aburner embodying my invention comprises a shell or casing, which is divided into front and rear compartments by means of a partition, 2. series of holes or perforations formed inlsaid partition, preferably adjacent to the edges thereof, an admission opening or tube to the rear compartment of said shell or casing, a discharge-opening from the front compartment of said shell or casing, a tube which extends through said shell or casing, the front or discharge end of which termi- A nates within the front compartment of the shell or casing and the rear or admission end of which projects without the rear end of said shell or casing, and spray-nozzles adapted to discharge fuel from the source of supply into and through said shell or casing and said tube.

The invention also consists in the various other features, combinations of features, and details of construction hereinafter described and then pointed out in the claims.

In the accompanying drawings a burner embodying my invention is fully illustrated.

Referring now to thedrawings, in which I have shown my improved burner as applied to a gasolene-torch, A designates the fuel tank or reservoir of said torch, which may be of any usual or approved construction and need not be described in detail, andB designates as a whole a burner embodying my in- The burner B is supported at the upper end of a tube a, which in the preferable construction shown communicates with said tank or reservoir A, at the bottom thereof, and extends upward on' the outside thereof, being supported at a distance therefrom. Said tube will thus always be exposed to and surrounded by air throughout its entire length, and will be kept cool thereby, insuring that said tank and its contents will be practically unaffected by the heat generated by the burner.

The burner B consists of a shell or casing B, which is divided into front and rear compartments b b by a partition or baffle-plate B said compartments being connected by means of holes or perforations 19 formed in said partition B In the preferable construction shown the shell or casing B is circular in vertical cross-section, and the holes or perforations. form a regular series extending entirely around said partition closely adjacent to the sides of the shell or casing. For convenience in constructing said burner and to render the interior thereof readily accessible the shell or casing B comprises several sections, which are secured together to form a rigid structure by screws or bolts 6 In the front end of the shell or casing B is formed a discharge opening or orifice b, which communicates directly with the front compartment b of the shell or casing and around the edge of which is formed an outwardlyprojecting flange b and the rear compartment 1) is provided with an admission pipe or tube 19 The discharge-orifice b is relatively large as compared with the admissiontube 19 and is located at the center of said shell or casing, while the admission-tube b is located eccentrically relativelythereto.

Extending longitudinally through the shell p or casing 13, concentric therewith, is a tube B the forward end of which terminates just within the front of said shell or casing and the rear end of which projects through the rear wall of said shell or casing, the extreme end thereof being practically flush with the end of the tube A screw 19 secures said tube B in position relatively to the shell or casing B. The size of the tube B depends upon the size of the flame which said burner is designed to create, being made larger or smaller, as the flame desired is larger or smaller.

Fuel to support combustion is supplied to the burnerB from spray-nozzles B 13 which may be of any usual construction and which are located opposite the rear ends of the tubes 7) and 13 respectively, and are adapted to discharge a spray longitudinally thereof.

Opposite the inner end of the tube 1') is a deflecting-surface against which the spray discharged into said tube is projected and which operates to distribute said spray to all parts of the shell or casing with substantial uniformity. As shown, the inner end of the tube 1) is bent at a sharp angle, as clearly shown at 19 thus forming the deflecting-surface desired.

The spray-nozzles B B are connected with the tube a by a passage b which comprises a tortuous section formed in the front end of the shell or casing B. Obviously when said burner is operating the contents of the passage b will be heated to a high degree and in the case of light oils converted into vapor or gas, in which form it will be delivered to the burner.

follows: for the shell or casing B about one and one-half inches in length by from one to three inches in diameter, for the dischargeorifice b from one-half to one inch, for the tube B from one-eighth to three-fourths of an inch, and for the pipe or tube Z) about fivesix'teenths of an inch.

The operation of myimproved burner is as follows: The passage from the tube 1) to the. discharge-orifice 6 being obstructed by the, partition or bafile-plate 3*, the draft created.

by the spray from the nozzle B will be retarded and will supply insufficient air to said The burner to secure perfect combustion. passage through the tube B being entirely free, the spray from the nozzle B will, on the otherhand, be surcharged with air.

orifice b, so that by properly regulating the Valves controlling the fuel-supplies to the therein,which register with each other, means I to project gaseous fuel through one of said passages or chambers together with more air than necessary to secure perfect combustion These; two supplies are blended at the dischargethereof, means to project gaseous fuel through the other of said passages or chambers together with less air than necessary to secure perfect combustion thereof, and means to regulate the amount of gaseous fuel and of air delivered to each of said passages or chambers, substantially as described.

2. In a burner, the combination of a passage-way or flue provided with a baffle and an unobstructed passage-way or fine, said passage-ways or lines being provided with admission-openings and with discharge-openings which register with each other and independent means to project fuel into each of said passage-ways or fiues, substantially as de scribed.
